MAXXimum HPC roughing

    The roughing module in hyperMILL® MAXX Machining offers solutions for high-performance cutting (HPC) with spiral and trochoidal tool movements. The package combines optimal milling paths, maxximum material removal and the shortest possible machining times.

    HPC tool paths for maxximum roughing results

    The roughing module is a comprehensive, high-performance package for creating spiral and trochoidal tool paths. Significantly increases material removal rates allow for extremely fast machining. At the same time, there is much less stress on the tools and machines. The roughing module is based on VoluMill™, a tried-and-tested best-in-class HPC technology from Celeritive Technologies.

    “Using hyperMILL® MAXX Machining means that we can rough steel with twice or triple the feedrate. In the case of aluminium, the factor is as high as four to five. Programming is so easy, it’s almost child’s play.”

    Mario Hausruckinger, CEO of NC-Technik HauKa GmbH

    High performance for all machining situations

    Users have maximum programming freedom for 2.5D, 3D or 5-axis machining Optimal cutting conditions combined with large Z stepdowns ensure extremely efficient 2.5D machining of grooves, pockets and prismatic workpieces. During 3D machining, hyperMILL® MAXX Machining divides the component geometry into different planes. The intelligent design and sequence of these planes ensure time and path-optimised machining. A comprehensive 5-axis HPC package allows spiral-shaped and trochoidal-like paths to be mapped to curved component surfaces.

    Maxximum reduction in machining times

    HPC roughing | reduced machining time

    hyperMILL® MAXX Machining reduces milling times significantly when compared with conventional roughing. Intelligent division into spiral and trochoidal tool paths allows for high-volume material removal.

    Maxximised tool life

    Full cuts are prevented with hyperMILL® MAXX Machining. Stress on the tool is reduced, significantly extending tool life, especially when harder materials are involved.

    Intelligent feedrate adjustment

    Special automated functions analyse the local component conditions – wrapping and speed at the edges – and automatically adjust the feedrates along the toolpath.

    Maxximum stock removal rate

    hyperMILL® MAXX Machining allows users to define minimum and maxximum feedrates for different machining situations such as during the approach, the plunge and for the actual machining in the plane.

    Intelligent division of cuts

    HPC roughing | large progressive ratios

    hyperMILL® MAXX Machining automatically recognises a machining situation with different planes and adjusts to the situation optimally. Material is removed with maxximum stepdown depth; the remaining material is then removed from the bottom up in defined intermediate steps.
